Need help with POS printer
I have a 100% Java POS application. The receipt printer is installed as the default Windows XP printer but on a USB port. I am using the Java Printable interface to print receipts. I insert the needed text, etc into a JLabel and print it. This all works fine. My problem is opening the cash drawer which is attached to the printer. I must send a 0x07 (ASCII BEL character) to the printer which then opens the drawer. For some reason the bel never gets sent.
Is the JLabel removing it? I know it is possible to send it through a Windows printer as there is a test provided with the printer and it works. I have also tried sending the 07 directly to the printer as a Java byte. I have tried opening both the Windows printer name and the USB port as files but that also does not work.
If anyone has an answer, I will forever be in your debt.
Thanks in advance,
